The most traditional omamori consists of an outer bag with inner totem, while morphic yōtan, bells, mallets, drums, and dogs represent other traditional forms. Morphic hyōtan omamori have no writing and consist of the shape of an object, such as a gourd. Morphic bells and mallets can be rattles or drum sticks; morphic drums and dogs have historical significance. Many of these traditional forms of omamori can still be found today. The Japanese believe that the kami reside in this world, in any objects, and with any powers. Therefore, sacred items are not limited to the traditional omamori bags; instead, many sacred items can have practical purposes. Some shrines sell pillowcases (to prevent senility) or hand towels (for traffic safety, to prevent workplace danger, and to provide wisdom in education).
